Calculate the LCM of 987,572,974,989,173

Given numbers are 987,572,974,989,173

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 987,572,974,989,173 is 47041865666796.

Find LCM of 987,572,974,989,173 with Prime Factorization


2 987, 572, 974, 989, 173
987, 286, 487, 989, 173

Multiply the prime numbers at the bottom and the left side.

2 x 987 x 286 x 487 x 989 x 173 = 47041865666796

Therefore, the lowest common multiple of 987,572,974,989,173 is 47041865666796.

LCM Formula to Find Lowest Common Multiple of 987,572,974,989,173

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

987 x 572 x 974 x 989 x 173 = 94083731333592

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

987 : 1, 3, 7, 21, 47, 141, 329, 987

572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572

974 : 1, 2, 487, 974

989 : 1, 23, 43, 989

173 : 1, 173

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,572,974,989,173, is 1.

Now, the common factors can be found like this.

987:3x 7x 47

572:2x 2x 11x 13

974:2x 487

989:23x 43

173:173

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 94083731333592/(1x2)

LCM = 94083731333592/2

LCM = 47041865666796

Thus, we can understand that the LCM of 987,572,974,989,173 is 47041865666796.
